実験手順
10% Pd/C (580 mg) was added to a solution of 7-methoxy-3-(4-methoxyphenyl)-3-(2-propenyl)thiochroman-4-one (1.75 g, 5.14 mmol) in ethyl acetate (20 ml) followed by stirring for 15 hours at room temperature under a hydrogen stream. Pd/C was removed by filtration through cellite and the resulting filtrate was concentrated under reduced pressure to give 7-methoxy-3-(4-methoxyphenyl)-3-propylthiochroman-4-one (1.7 g, Yield 96%).
